Today we are going to take a step back in time and enter the age of the dinosaurs. The dinosaurs are an extinct species of animal that began to live on the Earth over 200 million years ago. “Extinct” means that they no longer exist. The dinosaurs are some of the most intriguing and awe-inspiring animals that have existed on our planet. The dinosaurs’ colossal size, strange characteristics, and mysterious disappearance make them inherently worthy of study and interest. Even more than these reasons, the study of dinosaurs itself is an incredible adventure which requires thought and imagination. The study of dinosaurs helps you to appreciate just how mysterious and amazing nature really is. Our planet supports not only us and the animals that live today, but it even supported creatures as gigantic and strange as the dinosaurs- just think how cool that is! I hope that you bring a spirit of openness and wonder to your study of the dinosaurs, and that you come to appreciate the mystery and value of the dinosaurs. Today we are going to learn about the Allosaurus. The Allosaurus is one of the most famous dinosaurs in the scientific community because it is one of the most well-known dinosaurs. There is so much known about the Allosaurus because so many almost complete Allosaurus skeletons have been discovered. We are going to learn about what this particular dinosaur looked like, how it behaved, and how it interacted with other dinosaurs in its environment. We know what we know about the dinosaurs from a variety of sources including fossils, biology, and other scientific disciplines. Fossils are the ancient remains of the dinosaurs, the most familiar being their bones. Biological science is the study of life in general, but many scientists compare the dinosaurs to modern day animals to support their theories. Before a talk about dinosaurs can take place it is important that we discuss the theory of evolution. Evolutionary theory supposes that all the animals we know and see today are the direct descendants of animals that existed millions of years ago. The dinosaurs and other creatures that existed millions of years ago either died out or gradually changed into different animals. For instance, birds are considered to be surviving dinosaurs because their dinosaur ancestors survived the dinosaur extinction event (we will discuss this later). Remember that any time you see an * next to the name of a dinosaur, it means that a book has been written about this dinosaur in the Dinosaur Books for Young Readers series. Any word written in bold is an important scientific term which is defined in-text. Italics are used to denote the first time a dinosaur’s name is mentioned in the book.

Acrocanthosaurus Inside and Out by Kenneth Carpenter Pdf
How can paleontologists know what a living dinosaur was like more than a hundred million years ago, particularly when only partial skeletons remain? Focusing on one large carnivorous dinosaur, Acrocanthosaurus (“high-spined lizard”), paleontologist Kenneth Carpenter explains the process, pairing scholarly findings with more than 75 color illustrations to reconstruct “Acro” before readers’ eyes. In Acrocanthosaurus Inside and Out, he offers the most complete portrait possible of this fascinating dinosaur’s appearance, biology, and behavior. Acrocanthosaurus—similar in size to its later cousin Tyrannosaurus rex, but studded with large spines—roamed what is now the south-central United States 110 to 115 million years ago, during the Early Cretaceous. Carpenter worked on the most complete of the Acrocanthosaurus skeletons (nicknamed “Fran”) that has been found. Here he describes the techniques that tell us about Acro’s biological makeup, movements, and habits. Studies of joints reveal the range of possible motion, while bumps, ridges, and scars on the bones show where muscles, ligaments, and tendons attached. CT scans allow us to peer into the braincase, while microscopes afford a cross-sectional view of bones. These findings in turn offer an idea of how Acro stalked and ate its prey. Scientific evidence beyond the fossils provides avenues for further inquiry: What does the sedimentary rock encasing Fran’s bones tell us about Acro’s environment? What does our knowledge of Acro’s distant relatives, such as crocodilians and birds, imply about its heart and other soft tissues? Can our understanding of other animals explain Acro’s huge spines? Carpenter distills all this information into a clear, accessible, engaging account that will appeal to general readers and scholars alike. As the first book-length work on Acrocanthosaurus, this volume introduces a prehistoric giant that once stalked Texas and Oklahoma and offers a rare, firsthand glimpse into the trials and triumphs of paleontology.
The Mesozoic Era by Britannica Educational Publishing Pdf
Dinosaurs have captured the imaginations of children and adults alike since the first fossil discoveries mapped them onto our general body of knowledge. This book journeys to an era long before humans, where dinosaurs were once masters of land, sky, and sea. In addition to accounts of significant dinosaur species and their extinction, readers will learn about the major life forms, both plant and animal, alongside whom dinosaurs dwelled, as well as the geographical and environmental factors that affected their subsistence.
The famous bone beds of the Morrison Formation, formed one hundred and fifty million years ago and running from Wyoming down through the red rock region of the American Southwest, have yielded one of the most complete pictures of any ancient vertebrate ecosystem in the world. Jurassic West, Second Edition tells the story of the life of this ancient world as scientists have so far been able to reconstruct it. Aimed at the general reader, Jurassic West, Second Edition recounts the discovery of many important Late Jurassic dinosaurs such as Apatosaurus, Allosaurus, and Stegosaurus. But dinosaurs compose barely a third of the more than 90 types of vertebrates known from the formation, which include crocodiles and turtles, frogs and salamanders, dinosaurs and mammals, clams and snails, and ginkgoes, ferns, and conifers. Featuring nearly all new illustrations, the second edition of this classic work includes new taxa named since 2007, updates to the naming and classifications of some old taxa, and expanded sections on numerous aspects of Morrison Formation paleontology and geology.
